Mischa Barton

We usually love maxi dresses since they look effortless yet glamorous and work on almost every figure, but this one worn by Mischa Barton to the BritWeek launch party in London breaks the mold. We never knew a maxi could look so unflattering... what would Marissa Cooper (her stylish character on The O.C.) say?

Between the blousy sleeves and oversized, billowing skirt on this Teca by Helo Rocha number, it's adding so much unnecessary bulk to Mischa's frame. The large print all over isn't helping, either. The plunging illusion neckline tries to add some sexiness but it just can't make up for all of the other flaws on this frumpy frock.

The final verdict? This dress could be improved if it were sleeveless, streamlined and solid, but all of the extra fabric and busy print are ruining it. Just because maxi dresses are comfortable doesn't mean it should look like you left the house in your muumuu, Mischa.

Rumer Willis

Cutouts are super-hot and on trend right now, but you have to use them sparingly. Case in point: Rumer Willis, who clearly thought less (fabric) is more when she attended Elle's Women in Music event in Hollywood wearing this very risqué little black dress. Let Rumer be a lesson to us all: Be careful with cutouts.

The wide cutouts on the side of her legs were so revealing that she accidentally showed off her pink underwear while posing for photos. While we applaud her for wearing panties, we doubt she was hoping to reveal the exact color of them to us when she got dressed for the evening. The midriff cutout already showed plenty of skin... the side ones are way too much.

The final verdict? Rumer's funky pink-streaked hair is appropriate for an event paying homage to music and her studded clutch is cute. Next time, we simply suggest choosing cutouts on the top or bottom only and not all over. But hey, at least Demi's daughter didn't go commando. Thank you for that.
